Most of the new gears contain PIE/MND/SS/CRIT. Where has all the DET gone ?

While I'm very fine with MND/SS/CRIT, the PIE I'm receiving from the gears (currently lvl59 / i146) seems way too much.

I DO dps, quite a lot even, but even so, I end up most boss with around 50/60% of my mana (out of the gigantic 12k mp pool).

In fact, as this has been recurrent in my last runs, I ended up switching jewels to more DET/VIT/CRIT by using a few items that aren't primarily designed for healers.

At the current lvl, the loss of PIE (and a bit of MND consequently) seems rather insignificant compared to the benefits I get from using different gear.

Has anyone come to the same conclusion ? Maybe this changes radically at level 60 ? Generally speaking, any input about these emphasized 3.0 stats will be appreciated.
